Adhesive Product

Tack refers to the initial stickiness of an adhesive when it first contacts a surface, allowing for quick adhesion with minimal pressure. Bond, on the other hand, describes the ultimate strength and durability of the adhesive after it has fully cured or set. While tack is about immediate grip, bond is about long-term adhesion.

- Myth: All adhesives perform the same in all climates. Fact: Different adhesives have varied performance across climates. For example, some acrylic adhesives might perform better in cold environments, whereas rubber adhesives could excel in flexibility in varying temperatures.

- Myth: Higher tack always means a better bond. Fact: High tack can provide a quick grab, but the ultimate bond strength might not be as high as with some lower-tack adhesives like certain acrylics designed for long-term bonding.

- Acrylic Adhesives: Generally offer excellent performance in cold and humid conditions, with good UV resistance. However, they might become brittle in extremely cold temperatures.

- Rubber Adhesives: Typically perform well in hot and wet conditions due to their flexibility and moisture resistance, but might degrade faster when exposed to UV light without proper additives.

- Acrylic Adhesives: Naturally have better UV resistance and can be formulated to enhance this property further, making them suitable for outdoor applications where long-term sun exposure is expected.

- Rubber Adhesives: Usually have poorer UV resistance unless specifically treated or formulated with UV stabilizers.

- Rubber Adhesives: There's a higher chance of discoloration over time, especially if the adhesive contains components that can migrate into the vinyl or react with UV light.

- Acrylic Adhesives: Typically cause less discoloration, thanks to their chemical stability and lower propensity for chemical interaction with vinyl.

- The lifetime depends on environmental conditions, but generally:

  - Acrylic Adhesives: Can last many years, often outliving the material they're adhered to when properly applied.

  - Rubber Adhesives: Might have a shorter lifespan, especially in harsh conditions, but can still provide many years of service with the right formulation.

The thickness can vary by product, but typical filament tapes might have adhesive layers ranging from 1 mil (0.0254 mm) to several mils depending on the intended application and required bond strength.

- Rubber Adhesives: Often have lower shear strength but higher initial tack and flexibility, which can be beneficial for applications requiring some movement or vibration.

- Acrylic Adhesives: Generally provide higher shear strength, making them better for applications where materials are under stress or weight.

- Acrylic Adhesives: Typically offer superior chemical resistance, especially against solvents, oils, and acids, making them ideal for industrial environments.

- Rubber Adhesives: While resistant to water and some chemicals, they generally don't match the broad-spectrum chemical resistance of acrylics.

The working time, or the period during which the adhesive remains tacky enough to form a bond, can vary widely. For most pressure-sensitive adhesives (PSAs), you have from a few minutes to several hours to make adjustments. However, some specialized PSAs might offer extended working times for more complex applications. After 72 hours, the adhesive has reached its cured strength.
